中文摘要 | 本文以臺灣北部地區 38 個自計雨量站之 1 ∼ 24 小時時雨量記錄為對象發展北 部區域雨量強度公式。本文與過去研究較大不同處,在綜合站年法與引數法區域分析的概念 ,並以不須假設統計的分佈的無母數頻率分析方法為主軸來進行單站頻率分析。在建立參數 區域化步驟中,首先對水文均一區內各測站間的相關程度予以檢定,確定資料的獨立性,並 採用具短期降雨特性的平均年最大一日暴雨做為空間引數進行區域分析。研究結果發現,臺 灣北部三個均一區所發展之區域雨量強度公式在率定與驗証上均有合理分析結果。 |
英文摘要 | This study collected 1∼24 hours rainfall annual maximum series from 38 recording raingauges over northern Taiwan to develop regional IDF formula. The method proposed in this paper is different from the previous ones on regional rainfall anlaysis. It not only combines the concepts of station-year and index methods to develop the regional formula, but also utilizes the nonparametric frequency analysis method, instead of parameter method, in developing the IDF relationship for individual stations. As far as parameter regionalization is concerned, the intersite dependence in a homogeneous region is first studied in order to assure that data obtained from different sites are independent. It is found that using the average 1-day annual maximum series, rather than the average annual rainfall as index has made better performacne. The regional rainfall formulas generated in three homogeneous regions of northern Taiwan were found to have reasonable simulation and can be verified well. |
